Despite still reeling from the confusing ‘Yanny VS Laurel’ debate, the internet has been thrown another audio illusion that is probably even more absurd.

A mind-blowing clip shared by Twitter user ‘sirvinnyd’ is stumping netizens on a new level. While most had very strong inclinations towards what they witnessed in ‘The Dress’ and ‘Yanny VS Laurel’, they’re probably less sure with this version.

According to ‘sirvinnyd’, the audio clip will play either words “brainstorm” or “green needle” based on which of these you think of.

The original audio came from a Ben 10 toy review by YouTuber ‘DosmRider’. In case you’re wondering, the figurine is saying his name, ‘Brainstorm’.

This illusion is living proof that the placebo effect is real, powerful, and sometimes manipulative. Now you’ve seen—and heard—everything.

Get ready to be truly mind-blown in the video below.
